Orion StarSeeker IV 150mm GoTo Mak-Cass Telescope
Orion's biggest Maksutov-Cassegrain StarSeeker IV GoTo Telescope at 150 mm (5.9-Inches) aperture - combines motorized object-location technology with high-power optical performance at a great price. With its computerized database of over 42,000 celestial objects to explore, this smart GoTo telescope will lead you and your family on a guided tour of the stars on any clear night.
Featuring a compact, yet large-aperture Maksutov-Cassegrain optical tube with an extra-long 1800 mm focal length and f/12 focal ratio, the StarSeeker IV 150 mm Mak-Cass collects a ton of light with its big 5.9-inch objective lens for bright views. Thanks to its combination of substantial aperture and long focal length, this telescope yields super-sharp resolution at high magnifications, making it an ideal instrument for high-power views of objects in the night sky. You'll be amazed by the exceptional amount of detail this telescope delivers when observing the Moon's cratered surface, and by its ability to reveal subtle features on planets like Jupiter, Saturn and Mars. Deep-sky objects such as nebulas, star clusters, and brighter galaxies are also well within range of this compact power-performer.
Following a simple two-star alignment process, the Orion StarSeeker IV 150 mm telescope can guide you to interesting sights on any clear night with its GoTo database of over 42,000 objects. A handy, built-in "Tour" mode feature of the included GoTo hand controller makes it easy for anyone to explore the wonders of starry skies, no matter how familiar or unfamiliar you are with the night sky. Once the StarSeeker IV 150 mm GoTo Mak-Cass locates a target for you to explore, the single-arm Alt-Azimuth mount's internal motors will automatically track the object's apparent motion and keep it centered so you can enjoy the view as long as you wish.
This fourth generation StarSeeker telescope features dual optical encoders on each axis of motion which allow you to move the telescope tube either manually by hand, or electronically by using the directional arrows on the GoTo hand controller. To save time, battery life, and reduce motor wear, you can manually point the telescope towards the general area of a target object, then engage the tube lock and use the hand controller to let the GoTo mount finish the fine-centering of the object electronically.
This complete GoTo telescope setup includes a thorough assortment of useful accessories:
This 150 mm GoTo Mak-Cass features a big, 2-inch visual back so you can use optional 2-inch diagonals and eyepieces if desired (sold separately). A handy 1.25-inch step-down adapter is included for the 2-inch visual back to allow easy installation of the included 1.25-inch accessories.
The StarSeeker IV GoTo mount and its slanted, single-arm Alt-Azimuth design provides attached telescopes with 360-degrees of Azimuth motion and 90-degrees of Altitude motion for horizon-to-Zenith pointing. A quick-release narrow dovetail saddle makes telescope attachment nice and easy. The StarSeeker IV 150 mm features an upgraded cylindrical leg stainless steel tripod that is much sturdier than previous models and adjusts in height for comfortable use. Tripod stability is further enhanced with the included dual-purpose spreader plate/accessory holder, which keeps the tripod rigid and provides a handy area for stowing idle eyepieces and accessories. The entire telescope setup weighs 26.1-pounds for convenient transportability.
Since the StarSeeker IV 150 mm Maksutov-Cassegrain telescope can locate and track celestial objects with its motorized GoTo system, you can use it along with a camera or smartphone to take impressive pictures of the night sky. Capture stunning snapshots of the Moon, planets and more by attaching a dedicated astrophotography camera, or a combination of an Orion SteadyPix accessory and your own point-and-shoot camera or smartphone to the StarSeeker IV 150 mm Mak-Cass to explore the rewarding hobby of astrophotography. (Cameras and SteadyPix accessories sold separately.)
Each StarSeeker IV telescope is powered by 8 internally stored AA user supplied batteries. A 12V DC auto-lighter plug is included for use of optional 12V DC field batteries.
